The Chungará lagoon is the environmental jewel of the Lauca National Park, a mirror of the great summits of six thousand meters of altitude in this sector of the Andes of Chile and Bolivia. The road passes along the shore of the lagoon and could take your eyes off the white pyramids of Parinacota, Sajama, Acotango and the rest of the peaks that mark the Andean border of the two countries.
